An object of the present int/en openings 2 which are of a diameter as large as tion is to provide a construction in which the is permissible within the vertical width of the glass is movable and the wiper is stationaryg-thus wall' I, and secured to the rear face of thi's wall obviating the necessity for a'reciprocable'or other is a double'ring channelmem'ber 3"with the-chan movable member to sweep acrossth'e surfalceof nel of one ring opening intdthe channel of-the 10 the glass; which member, especially in connee other ring at their adjacent sides.

Each ring gear is also rante with 1-5 tended area and to provide an arrangement inner channel to receive a packing 5 interweawhereby substantially the entire area 7 of the upon the peripheral edge of the glass disk "B'W hi'ch windshield glass may be wipedc'lean and maincloses each of the openings 2 a d' e'ad i-l ed tained in that condition.

Each of these with when rotation is discontinued, or may be w p r 9 i p v y attached at I 0 to the pp r manipulated to sweep across the glass when the end of a rod II which is secured at its lower glass is held stationary; and also to provide end by a head l2 to the forward end of a shaft an arrangement of drive for the glass whereby l3 e te d g through an Opening in the Wa the glass framing may be'pivotally mounted to below each of the openings 2 which are closed swing to open position for the purpose of venby the disks 6 and on the inner end of this tilation. shaft I3 is a handle M by means of which the It is also an object to provide certain other shaft m y be turned to w n h W p r about new and useful features in the construction, arthe axis of said shaft and move it from engagerangement and combination of parts, all as herement with the glass and out of the range of inafter more fully described and shown in the vision of the driver.

accompanying drawing wherein, This shaft I3 is mounted Within a bearing l5 Fig. l is a rear elevation of a windshield showon the wall land this bearing is provided with 40 ing the construction thereof and illustrating a transverse grooves or notches in its outer end to form of power drive therefor, and be engaged by a rib [6 upon the head I2, and to Fig. 2 is an enlarged vertical section substanhold the shaft l3 moved endwise inwardly and tially upon the line 22 of Figure 1. thus normally hold the rib I6 in engagement with As ordinarily constructed, the body of a motor one of the notches in the bearing, a spring I! car is usually closed at its forward end above is S e ved 1 1 e Shaft between Said bearing the cowl, by means of a windshield comprising and hand e I4. Therefore, the Operator b P sa pivoted or otherwise mounted frame of subing forwardly upon the handle l4, may disengage stantially rectangular form for holding the glass, the head [2 from eng gement with the bearing this frame having little effect in tying together and swing the rod H and wiper 9 to the desired the sides of the body at its forward end. position either in contact with the glass or out In the present construction as shown in Figof contact therewith, and when so moved it will ure 1 the forward end of the body is closed by be held in that position by the re-engagement of a plate forming a wall I, which plate is rigidly the rib IS with the notches in the end of the secured at its ends to the side portions of the bearing IS. The wiper when in contact with the body and at its top and bottom sides to the roof glass is therefore held in a fixed position with be simultaneously rotated by providing ashaft,

I8 mounted in bearings andextending across the V peripheries of the two-ring gears, said shaft being provided with worms H! to engage the peripheral teeth of the, gears 4 and simultaneously rotate these gears in the same direction, power being applied to the shaft l8 through gearing 20 from an electric motor 2| which may be mount- 1 ed in any convenient position, this form of drive' providing for a simultaneous rotation of the glass disks in the same direction and also providing for the pivotal mounting of the double ring'chana nel 3, said channel with its ring gears and glass disks mounted therein, being pivotally attached to the shaft I8, by meansof ears 22 on the double 7 channel, each forming a housing for each worm l9 andrbeing adapted, to'swing the double channel about the axis of these worms, thedouble channels beingsupported by said ears to turn 'independently of the worm'l with said ring gear in contact with said worms. Thereforethe double'channel member which carries the ring gears 4 andtheglass disks 6 mounted therein, may be swung away from'the openings 2 in said wall and provide for the opening of the windshield. for

the purpose of ventilation. 7

It is obvious that the glass disks shown in Figures 1 and 2 maybe power driven as shown or' maybe rotated by means of hand power if so desired, and it is obvious that one'or'moreof these transparent disks may be employed. 7

Having thus fully described myinvention, what I Claim iS:,-'

1. A closure device for the front end of a motor. vehicle body, formed with a circular opening said.

device including a frame having a channel extendingalong the periphery of said'opening'said frame being pivotally supported at one' side of said openings to swing toward and from the same, a glass disk to close said opening; an annular member engaging the peripheral edgeof said disk and rotatively'moun'ted in said channel, a! g shaft forming the pivotal support for said frame,

means on said shaft for rotating said annular member, and a wiper for said disk.

2. A device for, the purpose. described including a body member having a circular opening, a

frame, a ring gear mounted on said frame for rotation about said opening, a glass disk mounted in said ring gear to'close said opening, a driving T'g'ear mounted in bearings at onesideiof said opening and in mesh with said ring gear, and

' means on said frame for pivotally supporting said: frame to swing toward, and from said opening with said driving gear maintained inmesh with said" ings, a ring gear'in each channeLia glass disk.

- withineach ring gear adaptedto'close saidopen ings, a shaft mounted in bearings upon said body member andextending adjacent the peripheries of, said ring gears, driving gears upon said shaft in mesh with said ring gears, ears projecting laterally from said frame through which said shaft extends for pivotally supporting said frameto swing toward and from said openings, said ears, being each formed with'a chamber to receive one of said driving gears and to turn about said gears upon the longitudinal axis of said shaft, whereby said driving gears are maintained in mesh with said ring gears and said frame is pivotally sup; ported to swing about'the axis of said driving gears toward and from said openings; 1
